IRIG-B TTL TO RS485 Converter
SPC - INS - 1010
Signals & Systems India Private Limited
The IRIG-B TTL signal is a time synchronization protocol that can be transmitted up to 50m maximum using coaxial cable. So the relay which is to be received the IRIG-B TTL signal may be far away from the IRIG-B source. The relay may be not able to synchronize with the GPS. To avoid such an incident in the field, some of the relays have provision to receive IRIG-B RS485 signal. The IRIG-B RS485 signal can able travel up to 1200m without any booster. All Time source equipment may not be supplied with IRIG-B RS485 signal output. The converter will act as a bridge between GPS Time source and Relays for time synchronization.

RS232 / RS485 / RS422 / Serial To Multi-Drop Fiber Optic Converters
Our advanced, rugged, industrial-grade, RS232 / RS485 / RS422 serial to multi-drop fiber optic converters are designed to cover large areas. These converters support up to 255 fiber nodes, and each fiber node can extend the RS232 / RS422 / RS485's distance to 3 miles (5km) for multi-mode converters and cables, or 25 miles (40km) for single-mode converters and cables. Depending on the site situation, these multi-drop fiber optic converters can be configured as a daisy-chain or a self-healing redundant ring fiber network. When configured as a ring fiber network, the built-in self-healing feature allows the data to be transmitted clockwise or counterclockwise; therefore, failure of any individual converter will not affect other devices located on the same fiber ring, making the entire data network more robust and reliable. These multi-drop fiber optic converters have been designed for harsh industrial environments and withstand a wide temperature of -40°F to 185°F (-40°C to 85°C), and they come with the options of multi-mode and single-mode, and ST, SC, and FC connectors.

PCI Express 2-Port
7203e
The 7203e PCI Express serial interface provides two optically isolated serial ports, each individually configurable for RS-232, RS-422, or RS-485. Each serial port utilizes a 16C952 UART with 128-byte Tx/Rx FIFOs that enables data rates to 460.8K bps for reliable high-speed communications in data-intensive applications. This high-performance UART includes 9-bit framing support and is register compatible with legacy 16550 software applications. In addition, the board derives a 62.5 MHz clock from the PCI Express link. This ultra-high-speed clock is divided by a flexible 8-bit clock prescalar with 1/8 steps to provide support for the widest range of standard and non-standard baud rates.
